three years of concentration threads, summarised so you do not have to read them

Discussionbranch of 6 comments

three years of concentration threads, summarised so you do not have to read them — a position I have arrived at slowly and would like tested. Why "more water" keeps confusing people, including me for a month. The vial contains a fixed amount of peptide. Water changes nothing about that amount. What it changes is…

If your calculation produces a fraction of a unit, the concentration is wrong for your dose. Change the water volume until the numbers land on whole units.

If your calculation produces a fraction of a unit, the concentration is wrong for your dose.

Right, and the arithmetic behind it: 15mg in 3mL is 5mg/mL, so 0.5mg is 10 units.

15mg into 3mL is 5mg/mL, and 1mg of that is 20 units

Correction: that gives 10 units, not what you have written. 20mg into 1mL is 20mg/mL and the division follows from there.

Are you accounting for the powder volume, or is that where the confusion is?

units are a volume on a U-100 syringe, not a dose

About c/reconstitution

The arithmetic and the technique. Bacteriostatic versus sterile water, reconstitution volume as a concentration choice, converting mg/mL into insulin-syringe units, dead space, swirl-not-shake, stopper coring, and how long a reconstituted vial is actually good for. Math errors get corrected fast and politely.

c/reconstitution rules
  1. Show your numbers. "How many units?" with no mg and no mL cannot be answered.
  2. Never post a calculation as advice without stating the concentration it assumes.
  3. No sterile-compounding-for-others discussion. Personal handling only.
  4. Independent community. Nobody here sells anything, and anyone who tries is banned.
  5. Not medical advice. Describe what you did; never prescribe to a stranger.
  6. Claims need evidence. Batch numbers, dated screenshots, independent test reports, or a citation.
  7. No referral links, discount codes or affiliate URLs. Permanent ban, no appeal.
  8. No contact handles, wallet addresses or tracking numbers — they identify people.
  9. Be recognisably decent. Disagree hard, insult nobody.

Before you read on

Several compounds discussed on GLP Research Hub are sold for research use only and are not approved for human use anywhere. Nothing here is medical advice and none of it is written by your clinician. If a post reads like an instruction, treat it as a description of what one stranger did.
